If someone could pass this on to our sponsors I would be grateful as I understand they may be liable to be fined, as well as the owner of the property, and I'd much rather they spent the money on sponsoring the Daggers.

In Redbridge you are not permitted to start building work until 8am Monday to Friday

Restricted hours for noisy building works

The Control of Pollution Act 1974 gives Redbridge Enforcement Team special powers to control noise on construction and demolition sites. Working hours can be restricted and conditions enforced on the machinery being used.

In Redbridge noise control hours are:

Monday to Friday from 8am to 6pm
Saturdays from 8am to 2pm
Sundays and Bank Holidays - No working

By the way, the property you are working on is now meant to have a council enforcement notice on it, after planning permission was refused three times. From where I am, it looks like the whole house might be subsiding, so do tell your workmen to take extra care.
